Objectives: We examine whether early-life enrichment, involving varied and stimulating activities to enhance cognitive function during childhood and adolescence, is associated with cognitive function in later life and whether the benefits persist over time. Methods: Growth curve models were used to examine up to five waves of data from the Health and Retirement Study-a nationally representative survey of adults 50 years and older (N = 10,070). We constructed separate measures of early-life enrichment to distinguish sources of influence (i.e., enriched home environment and enriched school environment). Global cognitive function was assessed with a modified version of the Telephone Interview for Cognitive Status. Results: Greater enrichment in each environment was incrementally associated with better cognitive function at baseline, but enrichment was not associated with change in cognitive function over time. Discussion: Receiving enrichment from multiple environments during sensitive periods of cognitive development may be advantageous for cognitive functioning in later life.

Objectives: This study examines the associations of ethnicity, caregiver burden, familism, and physical and mental health among Mexican Americans (MAs) and non-Hispanic Whites (NHWs).

Methods: We recruited adults 65+ years with possible cognitive impairment (using the Montreal Cognitive Assessment score<26), and their caregivers living in Nueces County, Texas. We used weighted path analysis to test effects of ethnicity, familism, and caregiver burden on caregiver's mental and physical health.

Results: 516 caregivers and care-receivers participated. MA caregivers were younger, more likely female, and less educated compared to NHWs. Increased caregiver burden was associated with worse mental (B = -0.53; p < .001) and physical health (B = -0.15; p = .002). Familism was associated with lower burden (B = -0.14; p = .001). MA caregivers had stronger familism scores (B = 0.49; p < .001).

Discussion: Increased burden is associated with worse caregiver mental and physical health. MA caregivers had stronger familism resulting in better health. Findings can contribute to early identification, intervention, and coordination of services to help reduce caregiver burden.

Objective: To characterize aging-related health in women with past CLSI and compare with women with no-CLSI.

Method: Health and Retirement Study Wave 11 and 12 data from women age >50 with CLSI were compared with data from women age >50 with no-CLSI. Generalized linear models were estimated for aging-related health outcomes.

Results: The group with CLSI (n = 230) was significantly younger than the no-CLSI group (n = 8035) yet had more physical, functional, and mental health challenges and fewer resources. Incarceration significantly predicted aging-related outcomes of multimorbidity, polypharmacy, mortality, frailty, and depression.

Discussion: Earlier onset of physical and functional health conditions in women with past CLSI has implications for health education and promotion, clinical practice, and intervention design.

Objective: Cross-sectional study to verify the association between dynapenic abdominal obesity and the occurrence of single and recurrent falls among Brazilian adults aged 50 years and over. Methods: Baseline data from the Brazilian Longitudinal Study of Aging (ELSI-Brazil), comprising 8374 individuals aged 50 years and over, were analyzed. Participants were categorized according to the report of falls, dynapenic abdominal obesity was determined by combining the presence of abdominal obesity (waist circumference) and dynapenia (handgrip strength). A multinomial regression adjusted for multiple variables was conducted. Results: The prevalence of a fall was 10.4% (95% CI: 9.7-11.2) and 10.8% for single and recurrent (95% CI: 9.9-11.9). Dynapenic abdominal obesity was associated with a single fall (OR: 1.3; 95% CI 1.1-1.7) and showed greater strength of association with recurrent falls (OR: 2.8; 95% CI 2.1-3.8). Conclusions: Our data showed that the coexistence of abdominal obesity and dynapenia in older adults creates additional challenges for aging.

Objectives: To synthesize the evidence on the relationships between physical housing characteristics or housing accessibility and different aspects of health among community-dwelling people 60 years and older. Methods: A systematic review of recent evidence with a narrative synthesis was conducted. Results: We included 15 studies and found three themes covering physical housing characteristics or housing accessibility that are associated with aspects of health among community-dwelling older adults: (1) interventions by home modifications targeting housing features both at entrances and indoors; (2) non-interventions targeting indoor features; (3) non-interventions targeting entrance features, that is, the presence of an elevator or stairs at the entrance. The overall quality of evidence across studies was assessed as very low. Discussion: The findings highlight the need for studies with a stronger research design and higher methodological quality that address the physical housing environment in relation to health among older adults to strengthen the body of evidence.

The current study investigated how pain and BMI trajectories mediate the influence of family stress (1991-1994) on later-life impaired functionality (2017) in women. The study used prospective data from 244 mid-older rural Midwest Caucasian women who were in long-term marriages over a span of 27 years. Within the structural equation framework, the analytical model used latent constructs of family stress and trajectories of pain and BMI to predict later-life functionality. BMI and pain trajectories mutually influenced each other in forming a self-perpetuating cycle over time in mid-older women. Further, midlife family stress shaped BMI and pain trajectories, and these trajectories had consequences for later-life functionality, as defined by three kinds of impairments: physical, cognitive (subjective memory), and social (loneliness). The findings emphasize the need for policies and interventions that focus on reducing women's stressful family circumstances in middle years to weaken and redirect their association with BMI and pain trajectories.

Objectives: This study examines healthcare resource use (hospitalizations, emergency department [ED] visits, and home health episodes) among adults 65 and older diagnosed with hearing, vision, or dual sensory loss (SL) seen in the primary care setting of an academic health system. Methods: Multivariable logistic regression models were used to examine the relationship between SL (identified using ICD-10 codes) and healthcare resource use for 45,000 primary care patients. Results: The sample included 5.5% (N = 2479) with hearing loss, 10.4% (N = 4697) with vision loss, and 1.0% with dual SL (N = 469). Hearing loss increased the likelihood of having an ED visit (OR = 1.22, CI: 1.07-1.39), and home health services (OR = 1.27, CI: 1.07-1.51) compared to older adults without any SL. Vision loss reduced the likelihood of having a hospitalization (OR = .81, CI: .73-.91). Discussion: Findings support research into the drivers of healthcare use among older adults with sensory loss.

Objectives: Identifying whether obesity is a risk factor for dementia is complicated by the possibility of weight change as dementia evolves. This article investigates an extended time path of body mass index (BMI) before and after incident dementia in a nationally representative sample. Methods: Using the Health and Retirement Study (2000-2016), we examine (1) the longitudinal relationship between BMI and incident dementia and (2) heterogeneity in the BMI trajectory by initial BMI level. Results: Weight loss begins at least one decade before incident dementia, then accelerates in the years immediately preceding dementia onset and continues after incident dementia. Those with higher levels of BMI at baseline experienced a much greater decline relative to those with a normal weight. Discussion: Our results help explain the contradicting findings in the literature regarding the relationship between obesity and dementia and highlight the need for using extended longitudinal data to understand dementia risk.

Objectives: This paper provides new estimates of disability prevalence for the archipelago and mainland-residing Puerto Rican populations ages 40 and above and compares disability by place of birth and place of residence to investigate drivers of middle and older age health. Methods: Large nationally representative samples from 2013 to 2017 American Community Survey and Puerto Rico Community Survey data are used to estimate age-specific disability prevalence for archipelago-born/archipelago-residing, archipelago-born/mainland-residing, mainland-born/mainland-residing Puerto Ricans. Results: Mainland-born/mainland-residing Puerto Ricans have the lowest age-adjusted disability rates and archipelago-born/archipelago-residing Puerto Ricans have the highest rates. Differences in education explain part of this disparity. Discussion: Similarities in disability prevalence are strongest based on where one was born as opposed to current residence, pointing to early life as a critical period in the disablement process for later-life health. Early life socio-economic disadvantage on the archipelago may have an enduring impact on later-life disability prevalence for archipelago-born Puerto Ricans.

Objectives: To examine birth cohort differences in depressive symptoms and life satisfaction in older men and women and the mechanisms underpinning the possible cohort differences. Methods: Two independent cohorts of Finnish men and women aged 75 and 80 were assessed in 1989-1990 (n = 617) and 2017-2018 (n = 794). They reported their depressive symptoms (CES-D), current life satisfaction, and evaluation of life until now. Results: The later-born cohort reported fewer depressive symptoms (8.6 ± 7.1 vs. 13.9 ± 8.3) and the differences were similar for the subdomains of depressive symptoms. The later-born cohort was more often mostly satisfied with life until now (90 vs. 70%) but not with the current life than the earlier-born cohort. Better self-rated health and education of the later-born cohort partly explain the cohort differences. Discussion: Older people in Finland report fewer depressive symptoms and they are more satisfied with their past life compared to their counterparts assessed 28 years ago.
